Hey guys! I played it and it looks very pretty. Very "chillout game".
I want there to be more aspects to my choice of placement that allow me to plan a little more.
Maybe Landmarks and Monsters give proximity bonuses to each other when placed within a certain distance so you're encouraged to leave room for them and make dense little islands.
Perhaps we could see the cards being added to the deck when we place a landmark so that when we draw them there's that mental link of "Oh! I have this because of that landmark I placed! My actions increased my options." I wasn't sure but I felt like I only got monsters after placing related landmarks so making that connection explicit would feel like I was picking my landmarks with more purpose beyond the direct point gain of placing them.
It reminds me a bit of Godus, where you clear land around certain buildings to encourage the expansion of those buildings to meet the needs of your people.
